Patent ZA-861195-B (ZA)
Title: Apparatus for collecting and discharging waste material
Inventor: BYERS EDWARD VICTOR
IPC: B65F/
Filed: 1986-02-18
Abstract: PCT No. PCT/GB86/00043 Sec. 371 Date Nov. 20, 1988 Sec. 102(e) Date Nov. 20, 1988 PCT Filed Jan. 23, 1986 PCT Pub. No. WO86/04268 PCT Pub. Date Jul. 31, 1986.Apparatus for collecting and discharging waste material comprises peripheral rows of teeth arranged on rotatable cylindrical shafts. The teeth on each shaft intercalate so that an entrapment zone for waste material is formed thereat during contra-wise rotation of the shafts. The teeth in each row pass through respective slits formed between the blade edges of rectilinear scaper blades placed between the rows and resting on the shaft. The scraper blades remove waste material from and between the teeth for discharge from the machine. To prevent the waste material being caught by cutting action between the leading faces of the teeth passing the scraper blades edges the magnitude of the angle formed at any time between those leading faces and the blades edges as the teeth pass through slits, has a value determined by the shape of the leading faces of the teeth and blade edges of the scraper blades so that the inducement of frictional engagement in relation to the materials being handled is never sufficient for a biting or cutting action to ensue.

Title: Improvements relating to fasteners
Inventor: PARKER GARY
IPC: E03C1/33
Filed: 2000-02-16
Granted: 2003-09-24
Abstract: A fastener for receiving a sink unit in a worktop has a plastics clip for attaching to a tab or rail and a hinged clamping member (11) which is tightened up against the underside of the worktop by a screw. The screw can be pressed through a bore in the hinge pin and self-tap into a non-threaded passage in the clip when the clamping member is hinged to engage under the worktop. The bore through the hinge pin has small flexible tags projecting into it past which the screw thread can snap, but which retain the screw when that is not engaged with the clip. The hinge pin and the clip have mutually engageable detents which locate the pin, and thus the clamping member, in either the operative position, for engaging the worktop, or the non-operative position with the clamping member swung back free of the worktop.

Title: Method and arrangement for guiding a user along a target path
Inventor: HULL RICHARD
IPC: G08B3/10
Filed: 2003-07-24
Granted: 2006-05-17
Abstract: An audio-based guide arrangement is provided for guiding a user along a target path by the use of virtual audio beacons. The user's current location is sensed and compared to the target path. Sounds are fed to the user, for example through stereo headphones, to simulate one or more audio beacons appearing to be located in a direction at least approximating the direction of the target path onward from the user's current position. Preferably, each successive location of the audio beacon is determined by determining a segment onward from the user's current position of a piecewise linear approximation to the target path, and setting the apparent location of the beacon at or relative to the end of this segment.

Title: Method for joining polyolefin pipes by fusion
Inventor: STAFFORD TREVOR GEORGE
IPC: B29C65/24
Filed: 1986-01-06
Granted: 1988-03-23
Abstract: The apparatus increases the hydraulic pressure in rams 16 until one pipe moves towards a heater plate 14. The movement is detected by a limit switch 26 and a microprocessor-based control system 28 adds a pre-programmed value of pressure to that pressure which caused the movement (drag pressure). The total pressure is applied to force the pipe ends against a heater plate 14 to form end beads (bead-up). After heating for a pre-programmed period the control system automatically initiates plate retraction and forces the pipe ends together (fusion) for another programmed period. The applied pressure is the sum of the recorded drag pressure and a pre-programmed added pressure. Operator judgement of bead size, pressures and time periods is eliminated. Pressurised fluid is supplied to the rams 16 from a pump and accumulator combination. The sense of ram motion is determined by changeover valves controlled by the control system 28.
